C++拦截窗口过程

 定义窗口过程： typedef LRESULT CALLBACK oldProc(_In_ HWND   hwnd,_In_ UINT   uMsg,_In_ WPARAM wParam,_In_ LPARAM lParam);oldProc* _oldProc;LRESULT CALLBACK webProc(_In_ HWND   hwnd,_In_ UINT   uMsg,_In_ WPARAM wParam,_In_ LPARAM lParam){return _oldProc(hwnd, uMsg, wParam, lParam);}调用的地方：_oldProc = (oldProc*)GetWindowLong(handle, GWL_WNDPROC);SetWindowLong(handle, GWL_WNDPROC, (LONG)webProc);
